BATTERY CONFIRMATION SYSTEM AND METHOD FOR CONFIRMING STATE OF CHARGE IN VEHICLE BATTERY
First Claim
1. A battery confirmation method for confirming a state of charge in a vehicle battery installed in a vehicle, comprising:
- connecting a tester to an onboard diagnostics connector of the vehicle;
obtaining a vehicle operating voltage from the onboard diagnostics connector when an electrical load of the battery is within a predetermined load range; and
determining a SOC value based on the vehicle operating voltage.

Abstract
A battery confirmation system and method for confirming a state of charge in a vehicle battery installed in a vehicle includes a vehicle having a controller, a battery powering the controller, and an onboard diagnostics connector operatively connected to the controller. A tester is connectable to the onboard diagnostics connector. The tester is configured to receive a vehicle operating voltage from the connector when an electrical load on the battery is within a predetermined load range and to determine a SOC value based on the vehicle operating voltage.
